I was previously running a Chaintech VNF3-250 mobo with an Athlon64 3200+ (C0 stepping with 1meg cache) with an enermax 435 watt whisper PSU and 9700AIW. I just bought a new Epox 8KDA3J and Antec 430 watt Truepower PSU to replace the subpar chaintech and loud PSU, but now i'm having trouble booting. Without plugging any drives in, just main components, the fans spin for about 1 second and shut off (with antec PSU). The video card seems to work fine in my nforce2 mobo, the cpu was working fine this morning and after switching it back still works in the chaintech. The Epox system will boot with a geforce3. So what's the deal? It doesn't seem like any component is actually broken per se - are they just not getting enough power? The funny thing is, my friend is running a system with almost the exact same components (same mobo, cpu, psu, 9700pro) and has no problems. All thoughts would be appreaciated.
